[SCSI] storvsc: NULL pointer dereference fix
If the initialization of storvsc fails, the storvsc_device_destroy()
causes NULL pointer dereference.
storvsc_bus_scan()
scsi_scan_target()
__scsi_scan_target()
scsi_probe_and_add_lun(hostdata=NULL)
scsi_alloc_sdev(hostdata=NULL)
sdev->hostdata = hostdata
now the host allocation fails
__scsi_remove_device(sdev)
calls sdev->host->hostt->slave_destroy() ==
storvsc_device_destroy(sdev)
access of sdev->hostdata->request_mempool
